You have to plug microbrute "Pitch Out" to minibrute "Pitch(to VCO".the notes played on the micro will be transposed on the mini by the value of the latest key you pressed(on the mini), left C key at octave 0 setting can indeed give you a 3 octaves transposition

right after power up, if you don't use the keyboard, it will be 0 transpose. then the lowest you can achieve with current firmware is +1 octave indeed. In the next Firmware update, I added a -3 octave switches position, that will enable you to get the missing octave (from 0 to +1). Exactly as it's done on MicroBrute.

Great thread. because, I'm such a rookie when it comes to CV gate , etc coming from MIDI. Anyway thank you... It plays on pitch.. Whewwww.. I was worried why the Microbrute only sequences the Minibrute on 1 pitch lol.. I didn't know about the Pitch out from Micro to Pitch to vco..
